How can I adapt the valve shown to 11/2" pvc to drain my gray water.
I'm off to Menards to get a few more parts for the water system but I cant figure out how to connect the drain valve. Any ideas? Anyone?
Thanks

There should be a piece that has a flange that bolts to the valve. Since it is ABS, you need a glue that will bond PVC to the ABS. they carry it at places like Home Depot. The adapter should be available at any RV supply store. Since that is grey water, you could use a PVC ball valve that might take up less room than the gate valve.......

...personally I would sh** can that gate valve and get a ball valve to replace it with...that PVC piping sure looks like a familiar configuration madjack p.s. as someone else said, there should be a flange that bolts to the valve...check with plumbing supply houses, RV places and places that sell hot tub repair parts...

...I have come to believe that, conflict resolution, through violence, is never acceptable.....................mj

I have a similar configuration of "plumbing" used as a grey water holding tank.
I'm using a 1/4 turn 1" ball valve, with the output end reduced to 3/4'".
The 1" outlet dumped it too fast, but now with a garden hose hooked up, the flow is just right, and I can "water" some of the trees just slightly away from my camp site...

Waiting for "someday" will leave you on your deathbed wondering why you didn't just rearrange your priorities and enjoy the time you had, instead of waiting for a "better" time to come along...

I figured it out at last. I cut a 4" piece of PVC and then flattened it in a vice with some heat from a torch. Then I took it in the house and when no one was looking I heated it in the toaster oven, until someone asked what the he** I thought I was doing. When I said I was making teardrop parts she offered to drop my parts, so I took it outside to finish. A little solvent welding and a little epoxy and I have a perfect dump valve. All I need to do now is adapt the output side to a smaller hose.
